Early in 2014 on the highway we were behind a semi (18 wheeler) and was going around it when suddenly a pebble hit the windshield. It started out minor but as the week passed it got worse. My husband insisted that it was okay but when the sun hit that crack I couldn't see a thing. It was a scary moment. Anyway, we call that place that comes to where ever you are and replaced it on the spot. Cost about $200+ but was well worth it. I can't remember the name but I was truly impressed with the process and would recommend it to anyone. Have you ever had this incident occur? Did you wait to have your windshield replaced until it became a safety issue?
